Patent EP-0215490-A2 (EP)
Inventor: OMOTO NORIAKI
IPC: H03J7/06
Filed: 1986-09-19
Abstract: An A.F.C. control system for reception of wide-band F.M. transmission such as satellite transmissions, in which a center frequency of an F.M. I.F. signal is repetitively and alternately compared with an upper and a lower frequency limit value so long as the center frequency lies between these values, with the results of the comparisons being respectively stored in two latch memories (28, 29), whose contents thereby indicate any error of the center frequency relative to the frequency limits. Any departure of the center frequency from between the limits is corrected by successive frequency shifts of the local oscillator (4) frequency, with the results of correction being indicated by the latch memory contents and with the number of frequency shifts being determined accordingly.

Abstract: A biotherapeutic process for preparing a patient-specific cytotoxic composition against a malignant tumor. Immune B-cell lymphocytes are obtained from in vitro and/or in vivo immunization with tumor cells. The immune B-cells are fused with myeloma cells or B-lymphoblastoid cells to form hybridomas which are then tested for production of monoclonal antibodies against the tumor cells. A plurality of selected hybridomas, each generating tumor-selective antibodies, are isolated and cloned and are used to produce monoclonal antibodies in large amounts. These antibodies are combined in a monoclonal antibody "cocktail" that will react with substantially all the tumor cells. The monoclonal antibody cocktail is linked with a drug, toxin, isotope or biological substance to form an immunoconjugate preparation which can be used, after appropriate preclinical safety and activity testing, for treating the patient with a custom-tailored therapeutic agent.

Abstract: An aromatic diol, e.g. hydroquinone, or a monoalkyl ether of an aromatic diol, e.g. the monomethyl ether of hydroquinone, is produced by transesterifiying a carboxylate ester of said aromatic diol or monoalkyl ether with an alcohol or phenol such as ethanol. A newly-formed ester such as ethyl acetate is co-produced by the reaction. The carboxylate ester is preferably produced by subjecting an aromatic ketone containing a hydroxy or alkoxy radical on the aromatic ring, e.g. 4-hydroxyacetophenone, to a Baeyer-Villiger oxidation.

Abstract: A gas separation membrane has a dense separating layer (10) about 1,000 nm or less thick and a porous support layer (11) 10 to 400 microns thick that is an integral unit with gra- dusily and continuously decreasing pore size from the base (11B) of the support layer to the surface of the thin separating layer (12). A method for making the membranes comprises casting a solution comprising ethyl collulose or an ethyl cellulose-bsaed blend in an amount from about 10% to about 35% by weight of the total solution in a volatile solvent such as Isopropanol, methylacetate, methanol, ethanol, and acetone. The solution contains also a nonsolvent eg water or formamide. The casting solution is cast in air from about zero to 10 seconds to allow the volatile solvent to evaporate and then quenched in a coagulation bath to remove the nonsolvent and then air dried.

Abstract: A planar magnetron sputtering device has an extended flat circular target source in opposed spaced parallel relationship with a generally flat article to be coated, placed within an evacuated coating chamber. Crossed electric and magnetic fields in the chamber are established in order to set up a plasma adjacent the target. The magnetic field is provided by a magnetic assembly of permanent magnets on the non-vacuum side of the target. The magnetic assembly is smaller in diameter than the target, but is mounted to a means for moving the assembly laterally over the entire area of the target. This means for moving sweeps the magnetic assembly in an eccentric path generally centered on the target center, with the path being non-reentrant and precessing about the target center with time. In this manner, the path sweeps different areas on successive rotations about the center, and a given area of target is exposed to the magnetic field at many successively different orientations. Articles are therefore coated with significantly improved uniformity and step coverage, while utilization of target material is improved.

Abstract: A magnetic rotary sensor according to the invention has a rotary drum (2) carrying thereon magnetically recorded codes representative of discrete primary positions obtained by dividing one rotation of the drum into a predetermined number. Further, an interval between the adjacent discrete positions identified by the codes is interpolated by interpolation signals (16, 17) generated on the basis of a sine wave signal (V x1 ) and a cosine wave signal (V x2 ), which are produced by magnetic signals being recorded on additional tracks (6, 7) on the drum (2) so that the periods thereof correspond to an interval of the position signals of the adjacent primary positions. 
     Accordingly, a magnetic rotary sensor can be realized, which is capable of identifying the rotational positions of a rotating body with the high resolution without increasing the rotary drum (2) in size.

Abstract: The pressure control arrangement for a breathing apparatus comprises a pressure-sensitive sensor element by means of which, both upon exceeding and falling below a pressure threshold which can be preset using a limit value device, a signal transmitter can be activated over a period of time which can be determined by means of a timer. The device is to be improved in such a way that a control of disconnection and/or stenosis in the lines of the breathing apparatus conveying the respiratory gas is possible even in the case of very small airway pressure variations, for whose control the known apparatus is insufficiently sensitive, and also in the case of slight variations in airway pressure maximums and minimums about a pressure median line. For this purpose, there is connected upstream of the timer (5) a comparator (1) for activating the signal transmitter (6) in each case upon exceeding of an upper pressure threshold and upon falling below a lower pressure threshold. <IMAGE>

Abstract: The invention relates to a process for the low pressure chemical vapor deposition (LPCVD) of metal silicide, especially molybdenum silicide, on a substrate at a low temperature. The walls of a LPCVD reactor which contains a heated pedestal for holding a substrate are cooled and the pedestal is heated so the substrate temperature reaches a desired level, depending on the metal silicide to be deposited. A metal halide and a silane or disilane are fed separately into the deposition chamber and mixed behind a small baffle plate at the entrance. The metal silicide is deposited on the substrate surface. It is preferred that the substrate be pre-treated with H₂ plasma before deposition.

Abstract: A helium cooling apparatus (l) according to the present invention comprises a refrigerator (2) for cooling a refrigerant. The refrigerator (2l) is con­nected with the proximal end of a transfer line (23), which is used to transport the refrigerant. A port (l8) with a predetermined diameter is formed in a liquid-­helium container (ll) which contains liquid helium. A condensation-heat exchanger (24), which is connected to the distal end of the transfer line (23), is inserted into the liquid-helium container (ll) through the port (l8). A heat-transfer surface of the heat exchanger (24) is formed with a plurality of grooves (50) extend­ing in the gravitational direction. The refrigerant is evaporated in the heat exchanger (24), and condensed liquid helium, adhering to the heat-transfer surface, drops along the grooves (50) when helium gas in the liquid-helium container is cooled to be recondensed. Accordingly, the heat-transfer surface cannot be covered with the condensed liquid helium, so that a wide heat-­transfer area can be secured. Thus, the heat transfer coefficient of the heat exchanger (24) is improved con­siderably. In this arrangement, therefore, the port (l8) of the liquid-helium container (ll), through which the exchanger (24) is inserted into the container (ll), need not have a large diameter.
